Negative trust members are not allowed. They can have a lot of experience and can give honest reviews if they are using this kind of service and have worked before.
Need to know a specific reason, I think I can give a good review, worked with a lot of mixing sites before but still cannot review here.

I've reviewing your cryptomixer website and its looks like the cryptocurrencies generator platform, and cryptocurrencies generators are always scammers... So how legit is your platform?
